    Three Phase Synchronous Motor Construction Working

    Athree-phase synchronous motorhas no starting torque. It has to be brought up to speed or as close to it as possible by some other means so that it can pull itself into synchronism. Once up to speed, the rotor field can be excited with direct current and the rotor is, in effect, then dragged around at the same speed as thethree-phasestator ...
